Gender, Role Models, Entrepreneurial Self-Efficacy And Career Intentions: Implications For Entrepreneurial Education, Ciara Marie Lavelle - O Brien
Theses
This thesis explores gender, role models, entrepreneurial self-efficacy and career intentions of secondary school students in Ireland. Most prior research includes entrepreneurial education as an important factor in the decision to start a business. Few studies include the importance of entrepreneurial perceptions, role models, self-efficacy, and career intentions combined and what implications this may have for entrepreneurial education. Previous studies cite the importance of role models for potential entrepreneurs but ignore how the role model is perceived or who the role models of this generation (Gen Z) are. This study used a semistructured questionnaire and the Repertory Grid Technique (RGT) …
Photoluminescence Properties Of Novel Iii-V Semiconductor Systems, Shumithira Gandan
Photoluminescence Properties Of Novel Iii-V Semiconductor Systems, Shumithira Gandan
Theses
Perturbation of the inherent radiation equilibrium in solids by an external energy could engender an emission of the superfluous energy as electromagnetic radiation, or luminescence. Photoluminescence methods precipitate this disintegration of radiation equilibrium often by supplying the external energy as photons with energies higher than the bandgap energy of the solid. Since the excitation energy momentarily transforms the medium before luminescence is emitted, photoluminescence experiments are able to produce diverse and intricate spectroscopic data detailing the optical properties of the solid as a measure of this transformation. The pliability of allowed electron states in semiconductors have instigated bourgeoning research in …

Digital transformation, alongside social media channels, influences policymaking. The aim of this research is to build knowledge of the consequences of digital transformation on lobbying at German federal level. This analysis uncovers how digital lobbying works in Germany and how it changes classic communication within the political sphere. Taking a grounded theory approach, the study addresses both communicating sides: lobbyists, on the one hand, and members of the German Bundestag and their employees, on the other. A profound understanding of, and differentiation between, lobbying and digital lobbying is gained through a first data-gathering step of 15 interviews with representatives of …
Predicting Carcass Cut Yields In Cattle From Digitalimages Using Artificial Intelligence, Darragh Matthews
Predicting Carcass Cut Yields In Cattle From Digitalimages Using Artificial Intelligence, Darragh Matthews
Theses
Beef carcass classification in Europe is predicated on the EUROP grid for both fatness and conformation. Although this system performs well for grouping visually similar carcasses, it cannot be used to accurately predict meat yields from these groups, especially when considered on an individual cut level. Deep Learning (DL) has proven to be a successful tool for many image classification problems but has yet to be fully proven in a regression scenario using carcass images. Here we have trained DL models to predict carcass cut yields and compared predictions to more standard machine learning (ML) methods. Three approaches were undertaken …
An Exploration Of The Experiences Of Modern Marketers: Skills Gaps, Mindset, And The Role Of Career Stage, Tim Crowley
An Exploration Of The Experiences Of Modern Marketers: Skills Gaps, Mindset, And The Role Of Career Stage, Tim Crowley
Theses
The digitalisation of marketing is the greatest change that the marketing profession has experienced (Kähler & Magnusson, 2018) and digital technologies now sit at the forefront of modern marketing (Thomas & Thomas, 2018). Digital marketing has numerous benefits (Kumar, 2015; Malar, 2016), however, digitalisation is disruptive (Mgiba, 2019) and has resulted in mismatched skills and an increased need for reskilling and upskilling (Bajpai & Biberman, 2019). Accordingly, skills gaps are evident (Crush, 2011; Day, 2011; Hege, 2020; Quinn et al., 2016; Royle & Laing, 2014; Wood, 2011). Notwithstanding, there is a scarcity of research in this area (Raghuraman, 2017; Royle …

The research draws on semistructured interviews undertaken with military and civil servant professionals from the Irish Defence Forces and the Department of Defence. Analysis of the interviews resulted in a number of new findings. The research highlighted the current deficiency in long-term funding and long-term strategic planning at the political level, and …
Smart Ageing And Renewal Through Entrepreneurial Skills Training, Sarah Davis
Smart Ageing And Renewal Through Entrepreneurial Skills Training, Sarah Davis
Theses
Globally, while the population is ageing, only 3% of older (≥65 years) adults are engaged in entrepreneurship. The Healthy Ageing agenda is responding to the population trends by increasing its focus on elements of active or productive ageing (incorporating older working) with quality of life as a primary outcome. Alignment and exploitation of the synergies between healthy ageing and older entrepreneurial engagement are lacking. Entrepreneurship education is broadening its focus and targeting inclusivity, albeit with as yet little focus on the older population. Older entrepreneurship, while tentatively linked with increased quality of life, has yet to receive direct attention in …

Defining The Potential Of Gene Therapy With Bone Morphogenetic Proteins As A Novel Therapeutic Approach In Parkinson’S Disease, Susan Rebecca Goulding
Defining The Potential Of Gene Therapy With Bone Morphogenetic Proteins As A Novel Therapeutic Approach In Parkinson’S Disease, Susan Rebecca Goulding
Theses
Parkinson’s disease is a neurodegenerative disorder, characterised by the progressive degeneration of midbrain dopaminergic neurons, and the intracellular aggregation of the α-synuclein protein in neurons throughout the nervous system. These changes result in the characteristic motor impairments in Parkinson’s disease. Current treatments are solely symptomatic and therefore there is an unmet clinical need to develop new disease-modifying therapies that can alter disease progression. For over 25 years, one proposed experimental therapy has focused on the delivery of proteins called neurotrophic factors to the brain to prevent dopaminergic neuron degeneration. However, to date, clinical trials using the most well-known neurotrophic factors …
Crop Salinity Tolerance Induction Using Novel Biostimulants (Saltibio), Elomofe Ikuyinminu
Crop Salinity Tolerance Induction Using Novel Biostimulants (Saltibio), Elomofe Ikuyinminu
Theses
Salinity is one of the major abiotic stresses affecting crop production, especially in arid and semi-arid areas. Most of the vegetable crops are salt sensitive, growing inadequately in salinised soils due to the accumulation of toxic ions from prolonged, inadequate irrigation programs. A meaningful approach to counteract salinity stress and increase crop yield is the use of protein hydrolysate biostimulants (PHBs). The main objectives of this study were to generate legume-derived PHBs by enzymatic hydrolysis, evaluate their ability to induce salinity stress tolerance in plants, and understand their mode of action. A full compositional and structural analysis of the generated …
